解析 从文章的最后可知, 作者及其同伴听到了老虎的吼声。那么, 接下来最有可能提及的当然是如何摆脱老虎。

　　During my travels through the mountains of Greece I was only ever scared once. It was dusk and as I walked alone I came across six large wolves that were feeding on the body of a dead animal. I had heard many stories about wolves as a child and it was this animal that I feared more than any other. The wolves before me were huge, at least 6 feet long and covered with thick grey fur.

As I approached, the wolves left the blood-covered snow that surrounded the body and started walking towards me, one after another. They stopped about 20 meters from me and stared. The lead wolf raised his head into the air and took in a deep breath, as if he was smelling my presence. The animals looked both beautiful and terrifying, but I knew I could not show them my fear. As I drew nearer, the lead wolf raised its head once more but this time let out a loud howl(长嚎). The awful cry rang out across the silent valley. I had never heard a more frightening sound. I was almost certain it signaled death.
